Radio Shack TRS-80 Model III User Manual

To
Our
Customers.
.
.
The TRS-80®
Model
III
Computer
is a
very
powerful
tool for
business
,
home
and
recreation.
Twenty
years
ago,
this
capability
would have
cost
hundreds
of
times as
much as
your
Model
III cost,
and
would
have
taken
up
an entire
room.
In spite
of its
power and
internal
complexity
,
the
Model
III can
be quite
simple
to
operate.
In fact, you
can
determine
just
how
"technical"
a
machine you
want it to
be.
At
the simplest
level
of
operation,
you can
use
Radio
Shack prepared
cassette
programs . All
you will
need
to
know is
how to
load and
run
a
cassette
program, and
how to operate
the
cassette
recorder.
If this
is
where you
want to
start, read
Chapters 1
through 6
in the
Operation
Section.
You may
also
want to read
about
CLOAD
and
SYSTEM in
Chapter
16 in
the
Language
Section.
If you
want to
write your
own
programs
and
you are a
beginner, read
Chapters
1
through 6
in the
Operation
Section,
then
start reading
the
book, Getting
Started
with
TRS-80
BASIC.
That,
plus
several
other
Radio Shack
books,
can guide
you
to
becoming a
programmer
in BASIC
and Z-80
language
(
'
'
machine
code
"
)
.
If you
already
know
BASIC ,
and
especially
if
you
have
experience
on a
TRS-80
Model I,
read the
entire
Operation
Section
of this
manual, as
well as
the
Appendix
which
compares
the
Model
I and
Model
III.
The
Model
III has
many
unique
features and
some
very
important
differences .
A
few
minutes
spent
before you
press
(ENTER)
could
save you
hours
later.
About
This
Manual
This
manual
contains
operating
instructions
and
a
description
of
Model
III
BASIC. It
is
arranged
for
easy
reference,
whether
you
are
seeking
simple or
technical
information.
Pages
are
numbered
sequentially,
and
there is a
comprehensive
Index
at the
end
of the
book.
If you
are a
beginner,
don't
worry
about
the
technical
parts in
the
Operation
Section.
The
beginning
of each
chapter is
for
you
.
(When
you
get to
the
POKE
statements
,
you
can
skip
ahead
to the
next
chapter. .
.
)
You
don
'
t need
to
read
past
Chapter
6. Then,
when you
learn
simple
BASIC
programming,
you can
return
and
try
out all
the
"goodies"
packed
into
your
Model
III.
Very
Important Note
Before you
even plug in
your Model III. read
Chapters
2
and
3
—no
matter how much
you think you know. This applies
whether you
have
a cassette-
or disk-based
system
.
Remember,
when all else fails, read the
instructions!
